ABSTRACT

A computer casing includes a support device, which extends outward from the surface of the computer casing. The support device further includes a support part, which juts out of the surface of the computer casing, and a plurality of joining parts, which juts out from the support part.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention is related to structure of a computer casing, andparticularly to a computer casing, which provides a support device tohold the radiation device.

2. Brief Description of the Related Art

Referring to FIG. 1, a computer usually includes a casing 11, a supportmember 12, a main board 13 and a radiation device 14. The casing 11 hasa plurality of connecting units 111 and the connecting units 111 have areceiving hole 111 a respectively to engage with the fixing elements 111b. The support member 12 provides a support part 122 and a plurality ofconnecting units 122 a are disposed on the support part 122. Each of theconnecting units 122 a has a receiving hole 122 b for engaging with afixing element 144 a respectively. The main board 13 is provided with aCPU base 131 to be attached with a CPU 132. The radiation device 14includes a cooling fan 141, a radiator 142, a retaining tool 143 and asupport base 144. The cooling fan 141 is fixed to the radiator 142 withfixing elements 141 a and the radiator 142 has hook receiving parts 142a to engage with hook parts 143 a of the retaining tool 143. Theretaining tool 143 has a receiving opening 143 b at both ends thereofand the receiving opening 143 b to fit with a projection 144 c of thesupport base 144. The retaining tool 143 has a receiving opening 143 cto fit with a further projection 144 b of the support base 144.

Referring to FIG. 2 in company with FIG. 1, while in assembling, thecooling fan 141 can be attached to the radiator 142 with the fixingelements 141 a. The radiator 142 is attached to the support base 144with the retaining tool 143 and allowing the bottom of the radiator 142contacting with the CPU 132. Further, the support base 144 is fixedlyattached to the main board 13 with the fixing element 144 a such thatthe support member 12 can be mounted under the main board 13. Finally,the main board 13 can be joined to the connecting units 111 of thecasing 11 via the fixing elements 111 b passing through the mountingholes 133 of the main board 13.

However, the preceding conventional computer casing has the followingdisadvantages:

The support member 12 is externally added to the casing 11 forsupporting the main board 13 and the radiation device 14 to avoid themain board 13 being deformed or damaged resulting from excessive weightof the radiation device 14. That is, the support member 12 can make upthe support strength of the main board 13. But, the support member 12makes the production cost of the casing increase a lot in order tostrengthen the main board.

The support member 12 being externally added to the casing 11 increasesthe gross weight of the computer and more parts have to be detachedduring repairing due to the support member 12 and this is one ofinconvenient factors.

SUMMARY OF THE INVENTION

A primary object of the present invention is to provide a computercasing, which has enough strength to support the radiation device.

Another object of the present invention is to provide a computer casingwith low production cost.

A further object of the present invention is to provide a computercasing with low material cost.

A further object of the present invention is to provide a computercasing, which can reduce the overall weight thereof.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. 3, a computer casing 21 according to the presentinvention in the preferred embodiment thereof includes a plurality ofconnecting units 211 and each of the connecting units 211 has anengaging hole 211 a for being engaged with a fastening element 211 brespectively. There is a support device 22 at the inner surface 212 ofthe computer casing 21 and extends upward from the inner surface 212.The support device 22 includes a support part 222 extending upward fromthe inner surface 212 and a joining part 223 extending upward from thesurface 222 a of the support part 222.

The support part 222 provides a shape of approximate “H” and the joiningpart 223 provides a shape approximate “X”. The joining part 223 has aplurality of connecting units 223 a and each of the connecting units 223a has receiving holes 223 b for being inserted with fixing elements 244a.

The computer is attached with a main board 23 and the main board 23 isprovided with a CPU base 231. The CPU base 231 is attached with a CPU232. The main board 23 has a plurality of mounting holes 233corresponding the engaging holes 211 a of the connecting units 211.

The computer is also attached with a radiation device 24 and theradiation device 24 includes a cooling fan 241, a radiator, a retainingtool 243 and a support base 244. The cooling fan 241 is attached to theradiator 242 with fixing elements 241 a and the radiator 242 is providedwith a hook receiving part 242 a for engaging with the hook part 243 aof the retaining tool 243. The retaining tool 243 at both ends thereofhas a receiving opening 243 b respectively and the receiving opening 243b fits with a jut 244 c on the support base 244 respectively. Theretaining tool 243 at the middle section thereof has a receiving hole243 c and the receiving hole 243 c can fit with a jut 244 b on thesupport base 244.

Referring to FIG. 4 in company with FIG. 3, the cooling fan 241 isfixedly attached to each other with the fixing elements 241 a and theradiator 242 is mounted to the support base 244 with the retaining tool243 and the bottom of the radiator 242 touches the CPU 232. Then, thesupport base 244 is fixedly attached to the main board 23 and the mainboard 23 is mounted to the support device 22. Finally, the fasteningelements 211 b pass through the mounting holes 233 to engage the mainboard 23 to the computer casing 21.

It is appreciated that contracting to the prior art, the computer casingof the present invention has the following advantages:

1. Due to the computer casing 21 of the present invention being workeddirectly to form the support device 22 for supporting the main board 23and the radiator 24, the main board 23 can endure weight of theradiation device 24 without being deformed or becoming damage. In short,the support device 22 can reinforce the structural strength of the mainboard 21. Further, the computer casing 21 needs less production cost andmaterial cost than the prior art.

2. The computer casing 21 is worked integrally to form the supportdevice 22 so that the gross weight of the computer casing 21 is reducedand it is facilitate to being set up.
